Background and topology:
Balance 380 hub connected (among others) to a MAX Transit Duo.
SpeedFusion/pepVPN configured using IC2 (hub topology)
On the Transit:
2 x Verizon Cellular connections (priority 1 for the VPN)
1 x Satellite (priority 2)
Starting at midnight on Nov. 26, the VPN connection consumed 100-150 MB per hour just maintaining the connection (no activity to speak of from the Transit’s clients).
According to the DPI report on the Transit, 75% is DNS traffic, and none of it initiated by clients (the usage reports list about 25 MB of client traffic, the remaining 100-135 MB being unaccounted for).
When I disconnect the two cellular connections (going to the satellite only) the extraneous traffic drops to zero.
I have tried modifying the alive-check, to no avail.
When I drop the VPN the extraneous traffic drops to zero.
Since we cannot afford to spend 100-150 MB/hour for each cellular connection to keep the VPN up, this is a matter of some urgent concern.
Please see attached for a copy of the DPI report (the flat line in the middle is the satellite-only interval).
I have rebooted the B380 as well as the MAX Transit Duo.
